What is a Biopesticide ? How are fungal parasites of insects useful in Biological control ?

Question

Ghissu Editorial · Accepted Answer

A biopesticide is a formulation derived from natural organisms such as bacteria, fungi or viruses, or their metabolites, that controls specific pests with minimal environmental harm. Entomopathogenic fungi like Beauveria bassiana and Metarhizium anisopliae penetrate insect cuticles and kill pests from within, giving lasting, residue-free control of whiteflies and aphids.

**Introduction**

Biopesticides are vital for reducing chemical pesticide hazards, promoting sustainable pest management, especially in states like ==Andhra Pradesh==. Their use aligns with environmental conservation and the growing demand for safer agricultural practices.

**Defining Biopesticides and Their Role**

1. **Biopesticide Concept**: Derived from natural organisms, biopesticides like microbial pesticides (e.g., Bacillus thuringiensis) offer targeted pest control with minimal environmental impact, backed by the BioE3 Policy⟦1⟧ and Bio-RIDE scheme that promote innovation and commercialization.

2. **Andhra Pradesh Context**: ==The state integrates biopesticides in horticulture and aquaculture, reducing chemical residues and supporting biodiversity.== Additionally, these practices help maintain soil health and protect beneficial insect populations crucial for crop productivity.

**Fungal Parasites as Biopesticides**

2. **Advantages and Challenges**: They provide long-term suppression and fit IPM programs but depend on environmental factors like humidity and temperature, and require farmer training for effective application and timing.

**Role and Benefits in Biological Control**

1. **Ecological and Economic Benefits**: Fungal parasites maintain pest populations below thresholds, reduce chemical use, lower health risks, and improve export potential, as seen in ==Andhra Pradesh’s== chilli farming. They also contribute to ecosystem balance by preserving natural predators.

**Way Forward**

1. **R&D and Production**: Boost research under Bio-RIDE and establish local production units to promote Aatmanirbhar Bharat in sustainable inputs. Tailoring fungal strains to local agro-climatic zones will enhance efficacy.

2. **Policy and Awareness**: Implement farmer education and provide subsidies to encourage adoption within IPM frameworks. Extension services should focus on proper usage to maximize benefits and overcome challenges.

**Conclusion**

Fungal biopesticides are essential for eco-friendly pest management and sustainable agriculture, offering a viable alternative to chemical pesticides while supporting environmental and economic goals.
